Abstract
This research presents the design process and user acceptance evaluation of a prototype rocket stove developed for household use. The design focuses on addressing the shortcomings of traditional stoves, with a primary emphasis on structural stability, safety, and ease of use. Under controlled conditions, thermal efficiency tests revealed that the prototype stove reached a maximum temperature of 266.4∘C, which was 157.5∘C higher than that of a traditional stove, and produced significantly lower smoke emissions. Subsequently, a user acceptance evaluation was conducted with a group of 10 users in the Ban Na Kha community, Satun Province, who trialed the prototype. The evaluation results indicated a very high level of acceptance for the rocket stove technology, with an average score of 4.74 out of 5. The most significant factors contributing to this acceptance were its robust structure and versatile cooking capabilities. These findings suggest that a design process that considers the user's context and is validated by empirical performance can effectively lead to the creation of well-accepted technology with strong potential for practical application.
